Application August 12, 1942, Serial No. 454,516

3 Claims.

This invention relates to new and useful improvements in wing nuts.

More particularly, the invention proposes to characterize the new wing nut by the fact that it is constructed from a strip of sheet metal of substantially rectangular shape with square bent portions thereof superimposed and having a pair of lugs along itssi'des bent and fashioned tosimulate the wings of a wing nut.

The invention is not limited to any particula form of blank from which the wing nut is constructed. Any number of such forms, and any number of Ways of bending the same may be developed. Several such modifications will be given in this specification.

Still further, in a modified form, the invention contemplates the provision of small prongs connecting the superimposed square bent portions to hold them from shifting laterally when the nut is being screwed down, under pressure, by using the wings.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a perspective view of a wing nut constructed in accordance with this invention and shown on a screw.

Fig. 2 is an end elevational view of the wing nut shown in Fig. 1.

Fig. 3 is a side elevational view of the wing nut shown in Fig. 1.

Fig. 4 is a perspective view of the blank from which the wing nut was constructed.

Fig. 5 is a perspective view of a modified form of blank for constructing a wing nut in accordance with this invention.

Fig. 6 is another perspective view of another modified form of blank.

Fig. '7 is a sectional view of a wing nut formed from the blank shown in Fig. 6.

Fig. 8 is another sectional view of a wing nut bent differently from the blank shown in Fig. 6.

Fig. 9 is a side elevational view of a wing nut constructed in accordance with another form of this invention.

Fig. 10 is a vertical sectional view taken on the line l0l0 of Fig. 9.

Fig. 11 is a perspective view of another blank from which a wing nut may be constructed in accordance with another form of this invention.

Fig. 12 is a side elevational view of a wing nut constructed from the blank shown in Fig. 1 1.

The wing nut, in accordance with the form of invention illustrated in Figs. 1-4, comprises a strip of sheet metal ill of substantially rectangular shape with square portions i l, [2 and I3 b'ent therefrom and superimposed, and having a pair of lugs [4 along its sides bent and fashioned to simulate the wings of a wing nut. The lugs I I are bent and fashioned from the lug blanks M as shown in Fig. 4. These lug blanks l4 are1ocated on opposite sides of the first one of said square portions, namely, the square portion l3. It is intended that the square portion l2 be bent along the line ab and superimposed on the portion I3, and that the portion ll be bent along the line cd and located beneath the portion It. The lug blanks I i are bent upwards along the linesae and bf and are also concave to add to their rigidity. The three superimposed bent portions are then drilled and tapped, indicated by reference numeral 15. The wing nut may then be engaged upon a screw P5 bolt or the like.

In Fig. 5 a modified form of blank is shown for making a wing nut in accordance with this invention. More specifically, the blank I0 is of substantially rectangular shape and may be divided into the several square portions ll, 12', and I3 which may be bent to be superimposed on each other. The blank I0 is also provided with lug blank portions 14' which are located along the sides thereof, and more particularly, one of these lug portions is on one side of the portion ll while the other lug portion is on the other side of the portion l3. In other respects this form of the invention is identical to the previous form.

In Figs. 6-8 other forms of the invention are shown which are very similar to the prior forms, distinguishing merely in the location of the lug blanks l4 and the bending of the blank to form the wing nuts. In accordance with this form of the invention the strip Iii may be divided into three square portions ll", l2" and 13''. The lug blanks Hi are arranged on opposite sides of the central portion I2". The end square portions H" and I3 may be bent, respectively, above and below the central portion 12 as illustrated in Fig. '1. In Fig. 8 another way of bending the blank is shown in which the square portions H and I2 are superimposed on the central square portion l2.

In Figs. 9 and 10 still another form of the invention is disclosed which is very similar to the form shown in Figs. 1-4, distinguishing in the fact that a plurality of spaced prongs l6 are formed upon the end of the portion I3 and engage in complementary receiving openings formed in the portion I2, while other spaced prongs I! from the portion ll engage in complementary openings in the portion 13. The interengagement of these prongs hold the various superimposed portions from shifting. This is particularly valuable when the wing nut is being used by turningon the wings thereof. This is av more rigid construction, and hence the wing nut may be made from thinner gauge sheet material.

In Figs. 11 and 12 still another form of the in- Y vention is shown in which the wing nut is formed from a strip of sheet metal 20 substantially of a rectangular shape having square bent portions 2! I and 22 thereof superimposed and having a pair of lugs 23 along its sides bent and fashioned to sim- I ulate the wings of a wing nut. The superimposed portions 2| and 22 are drilled and tapped; 1

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. A wing nut, comprising a strip of sheet metal of substantially rectangular shape with substantially square bent portions thereof superimposed and having a pair of integral lugs along its sides bent and fashioned to simulate the wings of a wing nut, said lugs extending normally from opposite sides of one of said bent portions.

2. A wing nut, comprising a stripfof sheet metal of substantially rectangular shape with substantially square bent portions thereof superimposed and having a pair of lugs along its sides bent and fashioned to simulate the wings of a.

V wing nut, and small spaced prongs from one of v the portions engaging complementary openings in the adjacent portion.

3. A wing nut, comprising a strip of substantially rectangular sheet metal divided into a plurality of substantially square portions bent one on the other, a pair of lugs extending outwards from the sides of said strip of sheet metal and bent and fashioned to simulate the wings of a wing nut, and prongs formed on the edges of the endmost square portions of said strip of metal and bent to engage complementary openings formed in the square portions adjacent said endmost square portions.
